Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional coil terminals on contactors are inflexible and can interfere with other components in tight spaces, making installation inconvenient and obstructing cable connections.
Innovation Solution
A pluggable coil terminal system with interchangeable insertion at both ends of the contactor, featuring interlocking coupler sections and a clamping structure to prevent movement and accidental unplugging, allowing for flexible installation and expansion of contactor functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed coil terminal is permanently installed on the contactor, then the connection is stable and reliable, but the installation flexibility is reduced and it may interfere with other components in tight spaces
Solution Approach 1:
The coil terminal is divided into separable parts: a pluggable coil terminal assembly that can be detached from the contactor body. This segmentation allows the terminal to be removed or repositioned, providing installation flexibility while maintaining a stable connected state when installed, thus resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The coil terminal transitions from a static fixed installation to a dynamic pluggable design. The terminal can be inserted into or removed from the contactor body as needed, allowing the system to adapt between stable connected state and flexible reconfigurable state, resolving the contradiction between connection stability and installation flexibility.
2Ease of operation
If the coil terminal sticks out on the exterior of the contactor body, then it allows easy cable connection, but it interferes with other functional components in tight installation spaces
Solution Approach 1:
The coil terminal is extracted as a separate pluggable component from the contactor body. When installation space is limited, the terminal can be removed or positioned to minimize protrusion, while still allowing cable connections to be made when needed, thus resolving the conflict between ease of operation and space requirements.
3Adaptability or versatility
If the coil terminal is made pluggable and interchangeable, then installation flexibility is improved, but the risk of accidental unplugging increases
Solution Approach 1:
A clamping structure is pre-configured within the contactor body that automatically engages with the coil terminal upon insertion. This preliminary action of pre-positioning the clamping mechanism ensures that once the terminal is plugged in, it is securely held, preventing accidental unplugging while maintaining the pluggable design for installation flexibility.
Solution Approach 2:
The clamping structure provides a preliminary counteracting force that prevents the coil terminal from being accidentally dislodged. By having the clamping mechanism ready to engage and hold the terminal firmly, it counteracts any unintended forces that might cause unplugging, thus maintaining reliability despite the pluggable design.
4Reliability
If a clamping structure is added to prevent movement and accidental unplugging, then connection stability is improved, but device complexity increases
Solution Approach 1:
The clamping structure is merged with the contactor body as an integrated component rather than a separate addition. This combining of the clamping function into the existing housing structure minimizes additional complexity while providing the necessary stability to prevent accidental unplugging of the pluggable terminal.

Implementation Method 1
said second coupler sections are capable of forming a conductive connection with any first coupler section within the coil framework due to their profiles interlocking
Implementation Method 2
there also being a clamping structure between the contactor housing and the coil terminal whereby when the coil terminal is inserted into the contactor, it prevents movement of said contactor housing relative to said coil terminal
Implementation Method 3
by passing electricity through the coil, an electromagnetic attraction is created between the static iron core and the moving iron core
